Hedman Header Col.Gskt.

The Mr. Gasket Hedman Header Collector Gasket (MPN 76) is a precision-engineered gasket designed for high-temperature engine applications where header-to-collector transitions demand reliable sealing. This 0.062-inch thick compressed fiber gasket features a 2.5-inch diameter opening and three-bolt mounting configuration, making it a direct fit for classic and performance engine builds requiring OEM-specification gasket replacement.

The compressed fiber construction handles sustained exhaust temperatures while maintaining a consistent seal under thermal cycling—a critical factor in headers where metal-to-metal contact alone cannot guarantee leak-free performance. The 3-bolt pattern ensures positive positioning and even clamping load distribution across the gasket face. At just 0.03 lbs, this gasket adds no measurable weight while meeting the durability demands of street, strip, and vintage restoration applications. Mr. Gasket's header gaskets are recognized throughout the performance engine community for maintaining seal integrity across repeated heat cycles without degradation.

This component serves engine builders, restoration specialists, and performance enthusiasts working on carbureted or fuel-injected platforms where original gasket deterioration or aftermarket header installation requires replacement. The 2.5-inch diameter is common across many classic V8 and small-block applications. Having a verified OEM-spec gasket on hand eliminates guesswork during teardown and reassembly, reducing downtime and ensuring the header joint seals properly on first assembly.

Header gasket selection often gets overlooked in engine builds, but a failed gasket leads to exhaust leaks, performance loss, and potential heat damage to adjacent components. The Hedman Header Collector Gasket is a consumable part with proven field history in the performance and restoration markets—exactly the type of specification component that separates professional builds from compromised installations.
